Lecture: Quantum Information

Quantum Information is concerned with the study of quantum mechanics from the point of view of information theory, as well as with the use of quantum mechanical systems for the purpose of information processing and computation. On the one hand, this includes quantum information theory, with topics such as quantum teleportation, the transmission of information through quantum channels, quantum cryptography, and the quantification of quantum entanglement as a resource for the aforementioned tasks. On the other hand, it involves quantum computation, i.e., computation based on the laws of quantum mechanics, covering topics such as quantum algorithms, quantum error correction, and the physical realization of quantum computers.

This lecture will provide a comprehensive introduction to the field of Quantum Information. Planned topics include

States, evolution, and measurement

Quantum entanglement

Quantum channels

Quantum cryptography

Quantum computation and quantum algorithms

Quantum error correction

Implementations of quantum information processing

Prerequisites

Solid knowledge of Linear Algebra is essential for this lecture. Knowledge of quantum mechanics is useful, but not necessary. (However, please let me know in advance if you have no prior knowledge of quantum mechanics.)

Material

Lecture notes and exercise sheets will be posted on this website. The L2P system will be primarily used for email communications.

The lecture takes place Thursday 12:15-13:45 in 26C401, and Friday 12:15-13:45 in 28B110. The tutorial takes place Monday 12:15-13:45 in 28B110, starting on April 27th.

Exercise sheets are posted on this website every Friday. Solutions should be handed in by the following Thursday, and will be discussed the following Monday. Tutorials are given by Mohsin Iqbal, and the problem sets are prepared by Anna Vershynina. 50% of the points for the exercise sheets are prerequisites for the admission to the exam, which will be an oral exam of 40 minutes.

There is an L2P site for the lecture, which will be primarily used to send out communications. Lecture notes and exercise sheets will be posted on this website.
